QUICK START HERE
1) Connect your Video Sources > Front panel Led CH1 CH2 turns on
This process is automatic, and there is no setting when you use HDMI or SDI
If you want to use other inputs you need to configure the video input first from the web interface
as described next on this manual
If one of the inputs is not valid or not connected, the ALARM led will turn on
The alarm led is one, for all the inputs, and turns on when one input is not valid
For your first test use a DVD or BLURAY or APPLE TV device
Do not use a computer for the first test as its video card might require additional configurations to
make it the same format as the dvd or bluray ( 720p / 1080i / 1080p @ 50 frames per second EU TV
Standard )
If you are using a computer out and the channel led on our front panel does not turn on, it means the video
format from the computer is wrong, not acceptable to run over coax to the TV Antenna mpeg decoder, so
you need to do a test with another type of source first, and then make the computer out the same as the
working source as per the specs above
FOR DIRECT TV BOX Connection :
1) SETTINGS>DISPLAY>VIDEO > native=ON / SCREEN= original
2) SETTINGS>DISPLAY>TV RESOLUTION > select 1080i and 1080p ONLY
all other resolution checkbox must be UNSELECTED
note: if your TVs are not FULL HD 1080, then you must select 720p
so the distribution will be in 720p only and your 720p TVs will decode it
FOR SKYBOX and similar satellite / terrestrial / cable decoder, FIRST connect it to the tv and change
the output resolution to FIXED 1080i or 1080P.
Audio MODE must be stereo uncompressed pcm, unless you set the audio pass-through mode for
dolby modes on our encoder settings ( see on next pages of this manual )
2) As First Test, connect a TV directly with a short piece of coax, then scan for digital channels
The found frequencies will show the channels on position 1 2 on the TV channel list
IMPORTANT : Make sure your TV ANTENNA MODE is set to DIGITAL, and scan for Standard STD
digital cable channels
IMPORTANT : If your TV is not receiving the channels, please test with another brand/model of TV as
Panasonic, Samsung, LG, Sony, Sharp, just to compare, as there might be some other settings on
the current tv that needs to be changed first.
3) After the above test is ok, you can connect the unit to your coax distribution and scan all the TVs to
find the channels
IMPORTANT : if you are not receiving the signal on the other TVs, please use the same first test TV
which was perfectly working, and move it step by step to the various locations through the coax, to
find where the signal stops.
There could be too much loss of signal on the coax, so you need to add a line amplifier, or there
could be a signal amplifier which is distorting the signal as our output might be too high and needs
to be lowered from the modulator web control page

AUDIO VIDEO INPUTS:
Your unit has 2 independent channels / inputs, each with analog & digital connectors, you can select via software per
each of the channels:
HDMI Input: Connect your Digital audio/video source with a single HDMI digital cable – For best quality solution
NOTE: you can use this port to input Dolby Pass Through stereo / 5.1 / 7.1
Component Input: Connect your RGB analog HD/SD video using the RED GREEN BLUE RCA
Composite Input: Connect your CVBS composite SD video using the YELLOW RCA out into the RED RGB input
Closed Captioning Input: Connect your CVBS CC signal to the YELLOW RCA marked CC
Analog L/R Audio Input: Connect your L/R analog audio to the RED / WHITE RCA marked AUDIO
RF COAX OUTPUT:
Your unit has 1 RF Coax out port, F-TYPE
This output is already amplified and goes directly to your coax splitter box from where all the coax cables distribute to all
your TVs.
This output is already amplified and usually does not require additional external amplifiers
The level can be adjusted up to +45 db millivots
IMPORTANT : SHOULD YOU USE EXTERNAL COAX AMPLIFIERS, YOU MIGHT NEED TO REDUCE OUR POWER
OUT IN ORDER TO AVOID SIGNAL OVER-DRIVE SATURATION / DISTORSION OF THESE AMPLIFIERS
The typical symptom is pixelisation or signal lost on the TV, please remove your amplifiers or reduce our power
out in single steps until the picture on your TVs is perfect.
Should you have a spectrum analyzer you can also adjust the levels through it for the perfection
Coax out : Connect to your distribution splitter to all the TVs. You can also connect directly to one TV full power without
any risk, as all the TVs supports +45dbmv input with no problem and have the AGC automatic gain control
Coax in: Connect to an incoming coaxial feed with third party channels, as from cable operators, or your indoor/outdoor
antenna. The injected channels are mixed with the VECOAX channels and output mixed to the RF OUT connector.
NOTE: The insertion loss is 6 db TYP, as any passive combiner, so you will need to compensate the incoming signal of 6
dB to get the same original level you apply to the input. You can also add a coax amplifier before entering the Coax in.
IMPORTANT: Cable providers might have special signals on their coax. It is a common practice to inject our
coax output to the coax combiner, avoiding to pass-through the cable operator coax feed and their special
signals through our unit, so we do not change their specific signal path.
IMPORTANT: Do your first tests on a simple test bench, connecting a test TV directly with a short piece of coax to
our RF COAX OUT, scanning for channels. Leave other channels feeds disconnected at first.

ASI I/O Ports ( option ):
Your unit has 1 ASI Input and 2 ASI Output BNC ports, to add transport stream data from any ASI external source, or
to feed any ASI device with the transport stream REMUX generated from the unit
Usually the ASI ports are not used.
Please see the related special ASI application page for more details.
REMOTE CONTROL NETWORK PORT:
Your unit has 1 RJ45 standard LAN Network port to remote control the unit from a computer
You can connect your Laptop with a simple network patch cord, directly, no need for a cross cable, then use your
favorite browser to setup and control the unit faster and easier.
Please refer to the Configuration Via Computer chapter for all the details.
DO NOT CONNECT THE REMOTE CONTROL PORT and the IPTV STREAMING PORT ON THE SAME SWITCH
REMOTE Control port should never receive ip streaming packets or could reduce responsiveness and control speed
IPTV STREAMING NETWORK PORT (option ):
Your unit has 1 RJ45 standard LAN Network port to stream the video channels over LAN/WIFI/WAN Networks.
The video channels can be played on any ip device through the proper video play application, mostly free downloadable
from internet.
Please refer to the IP STREAMING chapter for all the details.
DO NOT CONNECT THE REMOTE CONTROL PORT and the IPTV STREAMING PORT ON THE SAME SWITCH
REMOTE Control port should never receive ip streaming packets or could reduce responsiveness and control speed
USB Port:
USB is used for upgrade of the software

Configure Channel 1
Video Inputs & Encoders setup
On the web interface select INPUT 1 to control the audio video and assignment for channel 1
Copy the values on the picture for the best factory-standard settings
When done, Click the APPLY BUTTON to set the parameters

14
Configure Channel 1
Interface = Select the input connector/s you want to use, as HDMI or YPbPr Component or CVBS Composite
– default is HDMI
PLEASE NOTE: TO CONNECT COMPOSITE VIDEO CONNECT THE YELLOW RCA TO THE RED RGB INPUT.
The Yellow is for the closed captioning capture ONLY
Video Format = Select between MPEG2 and MPEG4 H264 video compression
– default is MPEG2
CC Switch = Select ON if you feed CLOSED CAPTIONING CVBS Signal to the YELLOW RCA,
otherwise leave OFF
– default is ON
Video Bitrate = Quality of the video
– default for MPEG2 = 19000 ( 19 Megabits )
ASPECT RATIO = Select between 16:9 / 4:3 or Auto for all formats
– default = Auto
LOW DELAY = Force the TV TUNER Mpeg Decoder to decode faster if your application requires low delays
– default is NORMAL – Works on any TV
– mode1 = FASTER ( 50 milliseconds encoding time )
– mode2 = Mid Speed ( 150 milliseconds encoding time )
– manual = Adjust the speed through the DTS parameter – 1= faster / 500= slower
While in manual you should set the GOP B frame to 1 and the Pframe to 6 for the best quality
Important: The Low delay mode 1 and 2 send I-FRAME only to the TV antenna mpeg decoder (fast mode)
If the TV decoder is not fast enough, it might drop frames.
If this is the case, use the manual mode, and find the best setting adjusting the DTS from 1 (fast) to a higher
value (reduce the speed). You might also try to use DTS 1 and increase the Value of Bframes from 1 to 2
or 3 ( max ) so help slower tv decoders to decode “ faster “
DTS Delay = Active only with the low delay – see above
GOP BFrame = Active only with the low delay – see above
GOP PFrame = Active only with the low delay – see above
Brightness = Adjust the Picture Brightness when the ANALOG INPUTS are used
– default = 128
Contrast = Adjust the Picture Contrast when the ANALOG INPUTS are used
– default = 128
Saturation = Adjust the Picture Saturation when the ANALOG INPUTS are used
– default = 128
HUE = Adjust the Picture HUE when the ANALOG INPUTS are used
– default = 0
Resolution = Not active when the AUTO CONFIG is selected
If Auto is selected, the transmission video size will be the same as the original.
Otherwise you can select the wanted down-scaling size so the picture will be scaled as needed, to fit lower resolution
televisions, or narrow-band networks / lower bitrates
– default = AUTO
Audio Format = Compression format for the Audio. You can select between the regular DOLBY STEREO AC3 and
MPEG2 / AAC, or PASSTHROUGH in case you feed the unit with dolby 5.1 or THX 7.1 so the original compressed
bitrsteam passes through as is.
Pass-Through works from HDMI in or from OPTICAL Audio in.
– default = AC3
NOTE: if your video source is only outputting compressed bit streams (5.1 / 7.1 / stereo) you might need to
change this to AC3 PASS HDMI if from HDMI or AC3 PASS SPDIF if from the audio optical input

15
Configure Channel 1
Dialog Normalization = FCC dialog norm value – required for some broadcast transmission
– default = -24
Audio Source = Select the input connector for the AUDIO, as HDMI digital or L/R Analog or Optical
If you need to feed HDMI video but take the audio from the L/R RCA connectors, switch this to Analog.
– default = AUTO ( follow the video hdmi or analog )
Audio Bitrate = Select the quality for the Audio
– default = 192 kilobits
Audio Gain = Boost or attenuate the audio level
– default = 100 ( no gain / no attenuation )

16
Configure Channel 1
Second TAB – Encoder Out Parameters
Copy the values on the picture for the best factory-standard settings
When done, Click the APPLY BUTTON to set the parameters
OUT Enable = Map this encoder channel to the wanted Modulator Frequency Output
This unit has FOUR frequency modulators ( RF1 / RF2 / RF3 / RF4 )
Each modulator can be turned on or off so you can decide to send out the two encoded channels on one single
frequency, or use one frequency per each encoder channel
In US QAM 256 the max bitrate allowed per frequency is 36 megabit/s, so only one full quality HD or UHD video can be
sent per channel.
When using MPEG2 video formats, the bitrate of one encoder channel might be too high to fit two channels in one
frequency, so it could be necessary to use two frequencies, one for each mpeg2 encoder, to allow the needed bitrate.
Most likely, when using H264 video formats, one frequency is enough to fit two full quality hd encoded channels.
In our example we will map the ENCODER 1 to frequency out RF1, the ENCODER 2 to frequency out RF2, and the USB
4K UHD player to frequency out RF3. The RF4 Frequency will be turned off ( not used )
The “MPTS” selector send the encoder stream also to the ASI out, in case you need ASI applications
– default = CHECK SELECT BOX “ RF1” – first on the left

17
Configure Channel 1
Service Provider = The name of the Headend (any id, or the name of the company ).
– default = PVI
Program Name = This is the Program name you want to assign to this channel
- make sure to use different names between the different channels of your unit to avoid conflicts
– default for the left column = HD1
SERVICE ID = Is the ID number of this stream.
- make sure to use different numbers between the different channels of your unit to avoid conflicts
– default for Input 1 = 1 ( displays 0x when saved )
PMT PID = Id of the PMT Descriptor Stream – do not change unless your application requires it
- make sure to use different values between the different channels of your unit to avoid conflicts
– default for Input 1 = 100 ( displays 0x when saved )
VIDEO PID = Id of the Video Stream – do not change unless your application requires it
- make sure to use different values between the different channels of your unit to avoid conflicts
– default for Input 1 = 101 ( displays 0x when saved )
AUDIO PID = Id of the Audio Stream – do not change unless your application requires it
- make sure to use different values between the different channels of your unit to avoid conflicts
– default for Input 1 = 102 ( displays 0x when saved )
PCR PID = Id of the PCR stream – do not change unless your application requires it
Usually this should be the same value as on the Video PID above, for this encoder channel.
Each encoder channel has a different video pid and the pcr should match the related video pid.
– default for Input 1 = 103 ( displays 0x when saved )
Major Channel Number = Is the DESTINATION MEMORY POSITION you want for this channel on all your TVs
as example BUTTON # 1
– default for Input 1 = 1 ( displays 0x when saved )
Minor Channel Number = Is the SUB-DESTINATION MEMORY POSITION you want for this channel on all your TVs
The combination of the MAJOR.MINOR channel makes the final memory position on the TVs.
The minor channel is mandatory to the TV to understand this is a DIGITAL TV Channel.
Channels with no sub channel number are ANALOG.
Most of the television will ignore the minor channel and recall the channel just with the major channel number IF there are
no other channel in the same frequency.
The minor channel cannot be Zero.
– default for Input 1 = 1 ( displays 0x when saved )
Source ID = Is the Reference number for this encoder. Every source must have a different id in order to avoid conflicts
when multiplexed together.
– default for Input 1 = 1 ( displays 0x when saved )
Short Name = Is NAME YOU WANT TO SHOW ON THE TVs for this channel. A max number of letters applies by the TV
standard.
– default for Input = HD1

18
Configure Channel 1
Status Box ( top right ) = Shows the current format for the incoming video and the current encoding bitrate
NORM = UNKNOWN > the video is not connected / the video format is invalid / the video is connected to a wrong
port respect the one selected.
( 50 OR 59.94 FRAMES PER SECOND )
Check the INTERFACE selector is set to the proper input.
Test with a DVD Player or a Bluray disk player FIRST.
DO NOT USE A COMPUTER AS VIDEO SOURCE AT FIRST as it might require settings to
output the same video format as the DVD or Bluray Disk devices, and might make confusion.
The TV OVER COAX MPEG Standard is only : 480i – 576I – 720P – 1080i – 1080p 50 / 59.94 FPS
If the Video Dot switches between Green/Red Continuously, your video source is feeding
a wrong video format, Not Suitable for the Video Over Coax distribution.
The limit is the TV TUNER MPEG DECODER over coax which cannot decode non tv standards.
In case your source does not support any of the TV Video format standard, you could use an external
scaler to convert any unknown non-tv formats to a valid tv format
NOTE : IF the video source works when connected directly (hdmi or video) to the tv, this is because
the tv is a slave monitor device when connected via video cable, different from when the tv
works receiving from the coax using its built-in coax MPEG Video receiver decoder
BITRATE = 0.0 > the encoder is not running, so the channel will not be found from TV scans

19
Configure Channel 2
On the web interface select INPUT 2 to control the audio video and assignment for channel 2
Copy the values on the picture for the best factory-standard settings
When done, Click the APPLY BUTTON to set the parameters

20
Configure Channel 2
Interface = Select the input connector/s you want to use, as HDMI or YPbPr Component or CVBS Composite
– default is HDMI
PLEASE NOTE: TO CONNECT COMPOSITE VIDEO CONNECT THE YELLOW RCA TO THE RED RGB INPUT.
The Yellow is for the closed captioning capture ONLY
Video Format = Select between MPEG2 and MPEG4 H264 video compression
– default is MPEG2
CC Switch = Select ON if you feed CLOSED CAPTIONING CVBS Signal to the YELLOW RCA,
otherwise leave OFF
– default is ON
Video Bitrate = Quality of the video
– default for MPEG2 = 19000 ( 19 Megabits )
ASPECT RATIO = Select between 16:9 / 4:3 or Auto for all formats
– default = Auto
LOW DELAY = Force the TV TUNER Mpeg Decoder to decode faster if your application requires low delays
– default is NORMAL – Works on any TV
– mode1 = FASTER ( 50 milliseconds encoding time )
– mode2 = Mid Speed ( 150 milliseconds encoding time )
– manual = Adjust the speed through the DTS parameter – 1= faster / 500= slower
While in manual you should set the GOP B frame to 1 and the Pframe to 6 for the best quality
Important: The Low delay mode 1 and 2 send I-FRAME only to the TV antenna mpeg decoder (fast mode)
If the TV decoder is not fast enough, it might drop frames.
If this is the case, use the manual mode, and find the best setting adjusting the DTS from 1 (fast) to a higher
value (reduce the speed). You might also try to use DTS 1 and increase the Value of Bframes from 1 to 2
or 3 ( max ) so help slower tv decoders to decode “ faster “
DTS Delay = Active only with the low delay – see above
GOP BFrame = Active only with the low delay – see above
GOP PFrame = Active only with the low delay – see above
Brightness = Adjust the Picture Brightness when the ANALOG INPUTS are used
– default = 128
Contrast = Adjust the Picture Contrast when the ANALOG INPUTS are used
– default = 128
Saturation = Adjust the Picture Saturation when the ANALOG INPUTS are used
– default = 128
HUE = Adjust the Picture HUE when the ANALOG INPUTS are used
– default = 0
Resolution = Not active when the AUTO CONFIG is selected
If Auto is selected, the transmission video size will be the same as the original.
Otherwise you can select the wanted down-scaling size so the picture will be scaled as needed, to fit lower resolution
televisions, or narrow-band networks / lower bitrates
– default = AUTO
Audio Format = Compression format for the Audio. You can select between the regular DOLBY STEREO AC3 and
MPEG2 / AAC, or PASSTHROUGH in case you feed the unit with dolby 5.1 or THX 7.1 so the original compressed
bitrsteam passes through as is.
Pass-Through works from HDMI in or from OPTICAL Audio in.
– default = AC3
NOTE: if your video source is only outputting compressed bit streams (5.1 / 7.1 / stereo) you might need to
change this to AC3 PASS HDMI if from HDMI or AC3 PASS SPDIF if from the audio optical input
